Zusammenfassung:A vibration damper and/or isolator for a rotating shaft is provided comprising a hub, an inertia element, a magneto-rheological elastic element interposed between the hub and the inertia element to non-rigidly couple the inertia element to the hub, and an electromagnet operable to produce a magnetic field across the elastic element when energized. The magneto-rheological elastic element, which may comprise a composite of magnetic-responsive particles dispersed within an elastic material, possesses a variable shear modulus that is dependent, at least in part, on the strength of a magnetic field applied to the elastic element.
